Foccus

Can't put your phone down? It's not your fault. Those apps were designed to keep you inside. Foccus was designed to keep them out. Foccus turns focusing into a game: shake your phone — and 3 randomly picked apps from your list get locked. Who's going? Instagram, TikTok, or that game you can't quit? Luck decides. That's why every session starts with the thrill of a lottery draw. THE REST IS UP TO YOU While the timer runs, your locked apps are off limits — try to open one and you'll hit a shield. Hold out, and every screen-free minute turns into points. Finish the session and the points, streak and badges are yours. Give up early... and your streak resets. Simple, fair, ruthless. HOW IT WORKS • Pick the apps that can be locked — just once • Shake your phone (or tap the dice) • 3 random apps get locked for 30 min to 3 hours • Resist, earn points, level up EVERYTHING THAT KEEPS YOU PLAYING • Points: every screen-free minute = 1 point, multiplied by completion bonuses and streaks • Daily streaks: complete a session every day and watch your multiplier grow • 6 levels: start as a Rookie, rise to Zen Legend • 8 badges to collect: from First Step to the 1,000 Minute Club • Screen-Free Time stats: the exact opposite of screen time — charts of the minutes you spent away from your phone THE SERIOUS PART Foccus is built on Apple's official Screen Time technology. The lock is real: you can't swipe it away or bargain for "5 more minutes." Watch the countdown live in the Dynamic Island — even when the app is closed. PRIVACY? ZERO DATA. Apple never tells us which apps you picked — so we couldn't share it even if we wanted to. No account, no sign-up, no ads, no tracking. Everything stays on your device. WHO IS IT FOR? • Students who reach for their phone mid-study session • Professionals who "just check something" and lose 40 minutes • Night scrollers glued to the screen before sleep • Everyone who started a digital detox and quit on day three — this time, the game is on your side Stop fighting your screen time. Turn it into a game and win. Shake. Lock. Focus. SUBSCRIPTION & PURCHASE Foccus Pro unlocks unlimited focus sessions.
